ABSTRACT 2-Substituted perimidine derivatives were synthesized by condensation of 1,8-diaminonaphthalene and the different formyl derivatives. Alkylation of the intermediate compounds was performed using microwave irradiation using potassium and cesium carbonate as a base. The synthesized compounds were characterised by UV and luminescence spectroscopies, cyclic voltammetry, thermogravimetry, differential
摘要 通过 1,8-二氨基萘和不同甲酰基衍生物的缩合合成了 2-取代的 perimidine 衍生物。使用微波辐射,使用碳酸钾和碳酸铯作为碱,进行中间体化合物的烷基化。合成的化合物通过紫外和发光光谱、循环伏安法、热重法、差示扫描量热法进行表征。它们表现出相对较高的热稳定性,热降解开始的温度范围为 230 至 392°C。大多数合成的嘧啶能够形成玻璃化转变温度高达 197°C 的玻璃。连接到 perimidinyl 部分的烷基会影响分子的构象,从而影响吸收和发射光谱。
